Abbé Joseph-Antoine Boullan (Saint-Porquier, Tarn-et-Garonne, 18 February 1824-Lyon, 4 January 1893) was a French Roman Catholic priest and later a laicized priest, who is often accused of being a satanist although he continued to defend his status as a christian.
He was a friend and inspiration of the writer Joris Karl Huysmans[1]. Huysmans with Henri Antoine Jules-Bois supported Boullan in a celebrated occultist feud with the Marquis Stanislas de Guaita.[2]
